For optimal auroral viewing, the Moon may not disturb because light from the Moon can be very bright which causes faint aurora to be barely visible, especially when the chances for auroral viewing are low. Below you'll find the Moon Phases for the current and next month so that you'll know exactly when the Moon will be a disturbing factor.
